Description

Technical Field

[0001] This utility model relates to the technical field of connectors, and in particular to a novel through-wall connector structure. Background Technology

[0002] Existing through-wall connectors generally include a terminal housing and a waterproof cover that connects to the terminal housing. The waterproof cover and the terminal housing are typically fastened together by snap-fit ​​or screws, as shown in the attached image. Figure 1 As shown, the waterproof cover has multiple buckles circumferentially arranged and a lateral sliding unlocking component. The terminal housing has multiple locking plates. When the left end of the terminal housing is inserted into the waterproof cover, the multiple buckles engage with the corresponding locking holes on the locking plates to connect the two. When it is necessary to separate the two, the unlocking component is moved to the right. The right end of the unlocking component drives the left end of the locking plate to open, causing the locking holes on the locking plate to separate from the buckles. Then, pulling the two in the opposite direction can separate them. This type of connector requires a separate mold for producing the unlocking component, which increases production costs. If the waterproof cover and the terminal housing are fixed with ordinary screws, water can easily seep into the interior at the screw connection point, resulting in a decrease in waterproof performance. Utility Model Content

[0003] In order to overcome the existing technical defects, the purpose of this utility model is to provide a novel through-wall connector structure to solve the above-mentioned technical problems.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0005] According to one aspect of this utility model, a novel through-wall connector structure is designed, comprising: a terminal housing and a waterproof cover. A nut is connected to the terminal housing. The waterproof cover is provided with a mounting groove and a through hole located at the bottom of the mounting groove. An anti-loosening screw is movably fitted at the through hole. A cylindrical and elastic rubber waterproof component is sleeved on the anti-loosening screw and located in the mounting groove. When the lower end of the anti-loosening screw is threadedly connected to the nut, the screw head of the anti-loosening screw presses against the rubber waterproof component to compress it. When the anti-loosening screw is not engaged with the nut, the rubber waterproof component supports the screw head, maintaining a gap between the lower end of the anti-loosening screw and the nut.

[0006] Compared to existing connector structures, this connector eliminates the need for an unlocking component, reducing manufacturing costs. When the terminal housing and waterproof cover are connected via anti-loosening screws, the screw head presses against the rubber waterproof component, causing its lower end to contact and compress the waterproof cover, preventing water seepage at the through-hole and achieving waterproofing. When the anti-loosening screw is loosened with a screwdriver, the rubber waterproof component elastically resets and supports the screw head, maintaining a gap between the lower end of the anti-loosening screw and the nut, facilitating separation. This single rubber waterproof component achieves both waterproofing and reset functions, eliminating the need for complex structures like spring-loaded reset mechanisms, resulting in better performance. Furthermore, the anti-loosening screw will not detach from the waterproof cover, facilitating quick connection between the waterproof cover and the terminal housing.

[0007] To better address the aforementioned technical deficiencies, this utility model also offers a superior technical solution:

[0008] In some embodiments, a sealing ring is fitted into the annular groove around the terminal housing, and the sealing ring makes sealing contact with the inner wall of the waterproof cover.

[0009] In some embodiments, the bottom of the mounting groove is provided with an annular groove, and the lower end of the rubber waterproof component is placed in the annular groove. This can achieve a better waterproof sealing effect.

[0010] In some embodiments, an annular groove is provided on the outer wall of the rubber waterproof component. This facilitates vertical compression of the rubber waterproof component.

[0011] In some embodiments, the top of the waterproof cover is provided with an annular protrusion, the interior of which forms the mounting groove.

[0012] In some embodiments, two mounting slots are provided, and anti-loosening screws are movably fitted into the through holes at the bottom of the two mounting slots. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0019] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] In the description of this utility model, unless otherwise explicitly defined, terms such as setting, installing, connecting, and fixing should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0021] refer to Figures 1 to 3 As shown, this utility model provides a novel through-wall connector structure, comprising: a terminal housing 1 and a waterproof cover 2. A nut 3 is connected to the terminal housing 1; the nut 3 is a common nut or an injection-molded nut. Multiple wiring terminals are provided inside the terminal housing 1. One end of each wiring terminal is connected to a wiring bolt and a wire clamping nut, and the other end is used to connect a wire. The waterproof cover 2 is provided with mounting grooves 11 and through holes 12 located at the bottom of the mounting grooves 11. There are one, two, or more mounting grooves 11; preferably, two mounting grooves 11 are provided in this embodiment. The bottom of each of the two mounting grooves 11 is provided with a through hole 12. Each part is equipped with a movably fitted anti-loosening screw 4, and each anti-loosening screw 4 is fitted with a rubber waterproof component 5. The rubber waterproof component 5 is cylindrical and located in the mounting groove 11, and is elastic. One or two or more annular grooves 51 are provided on the outer wall of the rubber waterproof component 5. In this embodiment, two annular grooves 51 are provided on the outer wall of the rubber waterproof component 5. A circular annular groove 13 is provided at the bottom of the mounting groove 11.
